C1, Week2, Exrecise 7 model_test

I have done the assignment and the result is as follows:

NameError Traceback (most recent call last)
in
----> 1 model_test(model)

NameError: name ‘model_test’ is not defined

i think the model_test function is missed. how can i reset the cell ?
thanks.

The function model_test is imported at the beginning of the notebook, the cell right after “1. Packages”

from public_tests import *

Could you please try to execute that cell and check again?

Thanks a lot. i run the first cell again
